Fecal microbiota transplantation for treating gastrointestinal graft-versus-host disease

Fecal Microbiota Transplantation in Patients With Acute Gastrointestinal Graft-versus-host-disease After Allogeneic Stem Cell Transplantation

Phase 3 Interventional Medical University of Graz · NCT03819803

What this trial studies

This clinical trial investigates the use of fecal microbiota transplantation (FMT) to treat patients suffering from gastrointestinal acute graft-versus-host disease (GI-aGvHD) following allogeneic hematopoietic stem cell transplantation (ASCT). The study focuses on patients with steroid-refractory GI-aGvHD who exhibit reduced bacterial diversity in their stool microbiota. FMT involves the infusion of healthy donor stool into the patient's gastrointestinal tract via colonoscopy, aiming to restore a healthy microbiome and alleviate symptoms of GI-aGvHD. The trial is designed to assess the efficacy and safety of this intervention in improving patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are patients experiencing their first episode of steroid-refractory GI-aGvHD with confirmed dysbiosis in their stool microbiota.

Not a fit: Patients with recurrent episodes of GI-aGvHD or those who have complications from previous colonoscopies may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life and survival rates for patients suffering from GI-aGvHD.

How similar studies have performed: Other studies have shown promising results with fecal microbiota transplantation in treating various gastrointestinal disorders, suggesting potential success for this approach in GI-aGvHD.
